Use logarithmic scale for speed bar gauge

Browse source 
The linear scale against WiFi 7 theoretical max (5760 Mbit/s) made real-world speeds look insignificantly low. A logarithmic scale gives meaningful visual feedback for typical connections (e.g. 300 Mbit/s fills ~66% instead of ~5%).

Bump version to 6.
